How to never look up tidyr pivot_wider and pivot_longer again

The video tutorial explains how to use the TIDYR package in R for reshaping data using the pivot longer and pivot wider functions. It introduces the concept of code snippets in RStudio, which help automate and simplify the process of data transformation. The tutorial provides step-by-step demonstrations of converting data from wide to long format and vice versa, using examples like the mtcars dataset and US rent income data. It emphasizes the importance of understanding the arguments required for each function and how code snippets can streamline the coding process.
